The control system includes: at least one tracking device of the point of maximum power or MPPT 2 adapted to adjust one of its input impedance seen from panels S for a power adaptation with panel S; at least one protection circuit of the system 3 adapted to avoid damages to the charge control system caused by inverted currents, coming from such battery B and from one or more electric equipment 8 connected with it.
Legal claims defining the scope of protection, as filed with the USPTO.
1. Control system for charging one or more batteries and electrically connected with one or more solar panels placed on a vehicle or boat, configured to obtain maximum transfer of power from said one or more solar panels and to control a charge of said one or more batteries of said vehicle or boat; said control system comprising: one tracking device of the point of maximum power or MPPT for regulating one inlet impedance seen from the panels for always having a power adaptation with the panel; at least a protection circuit of the system for avoiding damages to the charge control system caused by electromagnetic noises and inverted currents coming from said batteries, of said vehicle or boat, and from one or more electric plants connected with the batteries; said at least one protection circuit of the system comprising: an anti-reverse battery device for preventing inversions in charge flow of the batteries; at least one load-dump device or surge protection device, for avoiding damage of the system caused by high-voltage pulses; at least one cut-off device, for blocking and adjusting the charge of the batteries according to temperature of the batteries.
2. System according to claim 1 , further comprising an electronic control device for controlling: said one device MPPT; said at least one protection circuit; at least a controlling device for management of the power towards users; at least one telecommunication system, for data communication.
3. System according to claim 2 , comprising at least one operative configuration, selected among the following operative configurations: a) top speed working, wherein all devices are operating; b) stand by, wherein the electronic control device is kept on alert and a plurality of other devices is deactivated by reducing consumptions; c) deactivated, wherein all of the devices in the system are deactivated; d) diagnostic, wherein the system performs a diagnostic procedure.
4. System according to claim 1 , further comprising at least an auxiliary power supply producing one or more voltages of a predefined value by using at least a portion of the charge coming from the solar panels for supplying at least one of the devices comprised in the control system.
5. System according to claim 4 , wherein the system further comprises an actuating device which permits actuating the control system of the charge for a diagnostic procedure independently from a radiation with sunlight of said solar panel.
6. System according to claim 5 , wherein the actuating device comprises a remote control device which permits to configure the system in the operating configuration d) of remote diagnostic.
7. System according to claim 1 , wherein both the device with the anti-reverse-battery and the device with the load-dump protection are each implemented with at least one MOSFET power transistor.
8. System according to claim 7 , wherein the device with the anti-reverse-battery and the device with the load-dump protection are connected in series with the batteries.
